How It Works
How It Works
This formula combines three research-backed sleep ingredients that work through different pathways. L-Theanine promotes relaxation without drowsiness, 5-HTP supports serotonin production (which converts to sleep-regulating melatonin), and added melatonin helps regulate your natural sleep-wake cycle.
Who It's For
Adults who struggle to fall asleep, wake up frequently during the night, or want to avoid habit-forming sleep medications. Ideal for people dealing with stress-related sleep issues or those seeking a natural alternative to pharmaceutical sleep aids.
Who It's Not For
Not suitable for children, pregnant or breastfeeding women, or those taking prescription sleep medications without consulting their healthcare provider first.
About This Product
What It Does
Natural Factors Tranquil Sleep helps you fall asleep faster and stay asleep through the night without morning grogginess. Unlike habit-forming sleep medications, this natural formula works with your body's existing sleep mechanisms. The result is consistent, refreshing sleep that leaves you alert the next day.
Why It Works
- SUNTHEANINE L-THEANINE (200 mg): The clinically studied form of L-Theanine that promotes relaxation without sedation — unlike regular L-Theanine which can be inconsistent.
- 5-HTP (30 mg): Supports natural serotonin production, which your body converts to melatonin for healthy sleep-wake cycles.
- MELATONIN (3 mg): Works directly with your circadian rhythm to signal bedtime, helping you fall asleep more quickly.
